US Patent:

7766280, Aug 3, 2010

Filed:

May 29, 2007

Appl. No.:

11/754518

Inventors:

Thomas G. Cloft - Glastonbury CT, US
Richard H. Wiley - East Hartford CT, US

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

B64C 21/06

US Classification:

244208, 244209

Abstract:

An inlet flow control system disposed within a nacelle includes a panel on an inner surface of that nacelle. The panel includes a noise attenuation layer that dissipates noise energy. A vacuum source generates a pressure differential across the noise attenuation layer for drawing airflow through the panel and away from an inner surface of the nacelle.

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F01D 25/00
F04D 31/00
F04D 29/00

US Classification:

415144, 415116, 415226

Abstract:

A turbofan engine is provided that includes a core nacelle at least partially surrounded by a fan nacelle. The core nacelle includes a reflex nozzle providing a core exit. The core nacelle includes a contour on its exterior surface upstream from the reflex nozzle. The contour is generally conical and tapers toward the core exit at a first slope. The reflex nozzle tapers toward the exit at a second slope that is less steep than the first slope. The reflex nozzle includes a generally linear portion. In one example, the reflex nozzle is provided by a generally cylindrical extension that sufficiently turns the bypass flow away from the core exit so that the core flow does not become choked.
